Abstract

Samarium dopedbismuthtitanatethin films with the composition of and with strong preferred orientations along the axis and the (117) direction were fabricated on substrate by pulsed laser ablation. Measurements on capacitors showed that the -axis oriented film had a small remanent polarization of , while the highly (117) oriented film showed a value of at an electrical field of and a coercive field of . This is different from the sol-gel derived -axis oriented film showing a value of .
